Hoosier R7 DOT-R • 295/35 ZR19 (92W) • 040/C/A (Real World Details)

Hoosier's R7 is a track and competition radial tire designed for ultimate traction while complying with DOT regulations*. The R7 uses the same compound as the R6 tire it replaced but now incorporates a more rounded profile that extends the life of the tire's shoulders. The R7 features two symmetric "Formula One" style circumferential tread grooves. The R6 features a new, symmetric internal construction using nylon cord radial carcass plies reinforced by two lightweight steel belts and a spirally wrapped circumferential nylon cap ply under the tread. Tires begin with a 4.5/32" tread depth and do not require shaving though a thorough heat cycling before competition is preferred.
